How things work: 100 scientific explanations
Preservation property has always been important to humans. Historians in the ninth century were the first to record the use of varnish, a protective liquid composed of resins, natural oils, and alcohol, among other ingredients. Furniture makers learned that if they painted coats of the stuff on a piece of furniture or wood floor, it made it impervious to liquids and their damage and shielded it from normal wear and tear. And the makers liked the shine furniture had after it was varnished.
Varnish comes in many formulations. Some are oil based, using linseed or tung oil, while others are water-based. Varnish cures, or dries, on what it’s painted, creating a glossy, clear film on the surface. Some oil-based varnishes can turn to a yellowish color; water-based varieties do not. Wood must be carefully cleaned and sanded before any varnish is applied. Several coats are often required. All varnishes contain resins — terpenes with five-carbon molecules called isoprenes and also include a drying oil or solvent to reduce drying time.
Although furniture and flooors are still the most frequently varnished items, the wooden hulls of boats are also often varnished. Clear nail polish, a type of varnish, can be used for countless small fixes: dab small amounts to keep splintered wood from snagging, prevent ink from running, and stop buttons on clothing or screws on sunglasses from coming loose.

The four-thousand-year-old computer
In 1901, a group of divers excavating an ancient Roman shipwreck near the island of Antikythera, off the southern coast of Greece, found a mysterious object - a lump of calcified stone that contained within it several gearwheels welded together after years under the sea. The 2,000-year-old object, no bigger than a modern laptop, is now regarded as the world's oldest computer, devised to predict solar eclipses and, according to recent findings, calculate the timing of the ancient Olympics. Following the efforts of an international team of scientists, the mysteries of the Antikythera Mechanism are uncovered, revealing surprising and awe-inspiring details of the object that continues to mystify.
